Very probably a dumb question, but....

Maybe I missed it somewhere, but how do I retrieve an entity object from an entity collection, with the PK value? I really do not want to make another round trip to teh DB when I already have the collection of entities avaliable...

Maybe this should be added to the 'How Do I...' section....

create a new dummy entity, set the PK field(s) to the value you want to retrieve, set IsNew to false and use collection.IndexOf(dummy)
